To all whom t may concern: connecting the upper face of the foot portion e it known that l, EDMUND HT. MoRRis- 12 at one end and to one side of the longisnr, a citizen of the United States, residing tudinal center thereof. rllhe upper end of at Alton, in the county of Madison and State the shankportion 10 is formed with a cirof Illinois,r have invented certain new and cular bore to provide a socket 13 for engage- 60 useful Improvements in Attachments for ment on the free end of a presser foot bar a Shoe-Stitching Machines, of which the folofa sole stitching or sewing machine, the lat-4 lowing is aV specification. 'ter being preferably of a straight needle The invention relates to improvements in and awl type of shoe stitcher, suitable attachments for shoe stitching-machines, and threaded openings 14e being formed laterally 65 more particularly to a type of the same through the wall of the shank socket for the adapted for use in connection with shoe rereception of set-screw fastenings (not pair operations on such machines. shown) by means of which the presser foot The principal object of the invention is to is to be secured in operative position on the l5 provide for a novel fori'nof presser foo't bar a.- 70 construction, and one especially adapted for The foo portion 12 of the presser foot is effective operation during the rewelting of preferably cast in one piece with `the shank old shoes whereby the welt is applied to the portion 10, and consists of an elongated body shoe in a smooth uniform manner, and is of arcuate contour having its opposite side held in such condition throughout the -stitchwalls spaced on parallel curved lines where- 75 ing or sewing operation. by t-he working inwardly curved side wall Another object of the invention is to pro- 15 thereof is conformed to by the curvature vide for a presser foot of the character menof the shoe upper during the application of a tioned, and one embodying an extremely welt strip to the sole portion of the shoe. efficient guiding means for a welt strip, The heel portion of the foot 12 is undercut 30 whereby the same is pressed firmly onto-the to provide an inwardly extending curved surface of the sole, which is to be attached groove 16 gradually decreasing in width thereto, and is maintained in proper posiinwardly and which opens into the rear wall tion and against buckling during the stitchportion of a vertically extending substaning` or sewing operation. tially elliptical opening 17 while the toe por- 85 further object of the invention is to tion thereof is formed with the horizontal provide for a combined presser footy and welt elongated slot or recess 18 opening into the guide of the type set forth, and one which front wall of the vertical opening 17 and it especially designed to closely follow is'disposed in alinement with the opposed curved outlines or configurations of shoe upend of the groove 16, but in a plane slightly 90 pers immediately adjacent to or above the above the same. The vertically disposed points of connection of the same with the opening17 of the foot has its rearward porsole portionr of a shoe. tion'or wall, as at 19; extending upwardly With the foregoing and other objects in for a slight distance of the front wall of the 40 view, the invention resides in the certain forward portion of the reduced end 11 of 95 novel and useful. construction of the class the shank 10, the latter being curved in a mentioned which will be hereinafter more rearward direction from its point of conneclfully described, set forth in the appended tion with the foot portion, so that the socket claims, and illustrated in the accompanying 13 formed at the upper end thereof lies sub- Beferring to the drawing, the numeral 10 ing adapted to operate vertically through indicates the shank portion of the improved the opening 17 during the actuation of the form of presser foot, the same being circular latter. The forward lower edge of the toe in cross section and tapering downwardly to portion of the foot 12 is slightly bevelled or 55 provide a portion ll of a reduced diameter, curved, as at 20, 1n an upward direction, 11o

drawing, in whichzstantially in a plane vertically of the heel 1004 Figure 1 is a perspective view of the preportion, which arrangement gives clearance ferred embodiment of the invention, at the forward portion of the leg or shank Fig. Q is a vertical transverse section 10 for the proper vertical reciprocation of through the same, and, the needle bar b, which operates in parallel Fig. 3 is a bottom plan-view thereof. relation thereto, the needle c of the bar Z; be- 105 projected inwardly through the whereby to admit of the free passage thereunder of the adjacent portion of the shoe to be Welted and sevved.

In the use of a presser foot and Welt guide thus provided, the socket 13 is en-` gaged on the free end of a presser foot bar a, and is secured in desired adjusted position thereon by means of a set-screw, as shown in il 2, with the opening 17 thereof dis p pending from the needle bar and which opplane parallel to the presser footv erates ina bar a. The free end of a Welt nov.7 passed inwardlv through the slot 18 in the toe portion of the foot 12 and is trained across the lovver end of the opening 17 and groove .16 in the heell portion, and the machine will now be ready for the .velting operation. ln applying` the welt strip CZ to the upper face of the extended portions of thesole portion of the shoe to be rewelted, the sole extension (not shown) inserted beneath the lower face of the presserv foot so that the Welt strip` ci carried thereby is pressed rmly upon the surface thereof for the sewing operation, and as the shoe is turned for of the Welt entirely around the sion, the outer side Wall ofthe tion' of the strip [Z is sole eXtenupper porshoe vWillcontact the inwardly curved face 15 of the footA portion l2, 'Where by the welt strip Z Will be properly applied, and held uniformly sinooth throughout the sewing or stitching` operation, and is other- Wisesecurely held against buckling' under the thrust of the awl or needle at all times.

Having` thus fully described the invention, what is claimed, is

1. A presser foot for use in connection with the rewelting of shoes comprising a curved foot portion, a shank integral With said foot portion intermediate the ends of the latter, said foot portion and lower part of the front of the shank provided with a vertically disposed opening, said foot portion further provided with a horizontally disposed slot and a curved groove, said groove formed in the lower face of the heel t toe of the the laying on of the foot portion and extending inwardly and opening in the rear Wall portion of said opening, and said slot formed in the foot portion and opening into the front Wallportion of said opening, said slot disposed lin alinenient with the opposed end of said groove and in a plane slightly above the same. e

2,. Api-esser foot for use in connection With the reivelting` of shoes comprising` a curved foot portion formed intermediate its ends with a vertical opening and With a horizontal slot in the'toe thereof'coinmunieating with vsaid opening and `further provided in the` loweraface vof the heel thereof with a curved said opening, said groove gradually decreasingin Width toward said'opening.

A presser.A foot for use in connection with the rewelting` of shoes comprising a curved foot portion formed yintermediate its ends with a vertical opening' and With a horizontal slot inthe -toe thereof communieating With `said opening` and further provided in the lower face of the heel the'reotl with a curved slot communicating With said opening', said groove gradually decreasingh in Width toward said opening', said slot disposed in alinenient With the opposed end of said groove and in a plane slightlyabove' the same. Y Y p 4. A presser foot for use in coiinection with the reweltii'ig of shoes coniprising a footV portion of arcuate contour provided with a vertically disposed opening snbstantially elliptical in ysection andv further provided at the toe thereof with a horizontally disposed slot,communieating` with the front of said opening, said foot portion further having the lovver face of the heel thereof formed with a curved Lgroove communicating With the rear of said opening` and arranged slig'htly belen7 theplane of said slot. and a shank integral `with said foot portio n' intermediate the ends of the latter.`
